OIL-CUP. f

SPECIFICATION forming part of Letters Patent No. 609,204, dated August16, 1898.

Application filed October- 1,1897. are No. 653,766- (No model.)

To all whom it may concern:

Be it known that I, J AMESMACPHAILJL citizen of the United States,residing at West Pullman, in the county of Oookand State of Illinois,have invented a certain new and useful Improvement in Oil-Cups, which isfully set forth in the following specification, reference being had tothe accompanying drawings, in which- Figure 1 is a plan view of myimproved oilcup. Fig. 2 is a section of the same on the line 2 2 ofFig. 1. Fig. 3 is a similar section with the cover elevated to permit ofthe insertion of the oil. Fig. 4is a plan view similar to Fig. 1, butwith the cover and the spring removed. Fig. 5 is a front elevation ofthe cover. Fig. 6 is a side elevation of the cover, and Fig. 7 is a rearelevation of the cover.

My invention relates to an improved and useful oil-cup for bearings andis intended to produce an oil-cup that can be cheaply manufactured andthat will be durable in its construction, effective in operation, andincaa cylindrical casting forming a portion of the I bearing for ashaft, and B isthe oil-cup proper, which may be cast with the part A Onits outside the cup 13 may be of a cylin-' drical shape, and itsinterior surface may have the same general shape. An aperture D leadsfrom the oil-cup to the bearing for the purpose of permitting the oil inthe cup to reach the bearing.

In order to protect the cup from dirt,- I provide a cap or cover G,which consists of a flat plate having the outline shown in Fig. 1 andhaving the wing K projecting therefrom at substantially right anglesthereto. This win g K projects into the interior of the cup B and has aconcave bearing-surface II, which engages with the convexbearing-surface E, which forms one edge of the aperture 0, forming thetop of the cup. Projecting forwardly from the wingK is a lug L, which isopposed in position to a lug E, which projects rearwardly and downwardlyfrom the upper portion of the inner front wall of the cup B. A helicalspring M is interposed between said lugsF and L, and it will be seenfrom an insp'ectionof Figs. 2 and 3 that the action of this spring M,cooperating with the lugs F and'L, is to hold the cover G firmly downupon the top of the cup B and prevent any dust or dirt from enteringsaid cup. When one edge of the cover is lifted to the position shown inFig. 3, the spring M is put under increased tensionand immediatelyreturns the cover G to its normal position as soon as it is released. Apair of ribs J arelocated on the under side of the plate or cover G andserve to strengthen said cover and to assist in holding the cover in itscorrect position, as when the cover is down. The ends of the ribs J aresubstantially against the front edge and sides of the aperture 0. Forconvenience in raising the cover I form a portion N of the cover G,which overlaps the cup B, as clearly shown in Fig. 2, and forms aprojection to be grasped in raising said cover. The two principal partsof this oil-cup are cast, and they, with the spring M, constructed andcombined as shown, furnish a dust-proof cup that can be cheaplyconstructed and cannot readily get out of order.

Having described my invention, what I claim as new, and desire to coverby Letters Patent, is

1. An oil-cup consisting of the cup proper having an aperture, and apivotal bearingsurface on the inner edge of said aperture, with thecover having a pivotal bearing-surface cooperating with said otherbearing-surface and adapted, when closed, to rest upon the top of thecup, and a spring interposed between said cup and said cover to hold itnormally closed, substantially as described.

2. An oil-cup comprising the cup B having the pivotal bearing-surface Eand the lug F, with the cover having the bearing-surface H and the lugL, and the spring M interposed between said lugs.

3'. An oil-cup comprising the cup proper having the pivotalbearing-surface and the lug F, with the cover having the lug L, and theoverlapping portion N, and the spring interposed between said lugs,substantially as described.

4:. The oil-cup comprising the cup B having the aperture 0, thebearing-surface E, and the lug F, with the cover Gr having thebearing-surface H, the ribs J, and the lug L, and the spring M, allcooperating, substantially as and for the purposes described.

5. In an oil-cup for bearings, the cup proper cast integral with thebearing, and having an aperture and a'pivotal bearing-surface on theinner edge of said aperture, with the cover having a pivotalbearing-surface cooperating with said other bearing-surface and adapted,when closed, to rest upon the top of the cup, and a spring interposedbetween said cup and saidcoverto hold the bearingsurfaces in contact andthe cover closed, substantially as described.

6. An oil-cup comprising the cup proper having an aperture, saidaperture having a pivotal bearing-surface on one edge thereof,

with the cover for said aperture having a pivotalbearing-surface on oneside thereof cooperating with said other bearing-surface, an armprojecting into said cup, and a spring in said cup interposed betweensaid arm and cup to hold the bearing-surfaces in contact and the coverclosed, substantially as described.

7. An oil-cup for bearings comprising a cup proper having an aperture, acover pivoted at the inner edge of such aperture and having an armprojecting into the cup and a spring abutting at one end against the armand the other end against the cup at a point substantially opposite theedge of the aperture upon which the cover is pivoted.
